“Examine each question in terms of what is ethically and aesthetically right, as well as what is economically expedient. A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise.” - Aldo Leopold
The City of Dallas landscape zoning ordinance originated on March 1, 1986 under Chapter 51. On April 25, 1990, the City Council passed a resolution 'to support the protection and preservation of trees across the city.' The amended current version of the landscape ordinance under Chapter 51A, attached to a new tree preservation ordinance, became effective on May 25, 1994. There have been a few amendments to the three divisions of Article X (General, Landscape, and Tree Preservation, Removal and Replacement) in the years since its inception. On June 27, 2018, the Dallas City Council unanimously approved the Article X Landscaping and Urban Forest Conservation ordinances. It is in effect as of July 2, 2018.
